Rear right lense
You say you need a new gear stick, but is this an early spring loaded one that is supposed to be pushed down to get reverse gear? And has it broken? If this is the reason you need another, don't bother. You don't need the spring loaded split gear lever. The later cars dispensed with it. All you need to do is remove the detent gate bolted down at the bottom and 'throw it way'. Then weld the upper and lower parts of the gear lever together to form on sold lever, and you are back in business. If it is the rubber sleeve you need that is glued on to the lever shaft, you can still get new ones. I have seen them for sale a few times.
The rear lenses are unique and generally unavailable since anyone who has a spare is likely to hang on to it! New ones if you find one will cost possibly 200 Euro.
